Das Konzept der Nettosozialleistungsquote (NSLQ) von W. Adema hat in jüngster Zeit einige zentrale Annahmen der vergleichenden Wohlfahrtsstaatenforschung erschüttert. Nicht nur die quantitative Dimension des Wohlfahrtsstaates in OECD-Ländern, sondern auch seine strukturelle Zusammensetzung...

Mit dem kürzlich verabschiedeten Gesetz zur Reform der Professorenbesoldung soll über eine leistungsorientierte Entlohnungsstruktur auf der Grundlage objektiv messbarer Kriterien eine Verbesserung der Effektivität und Qualität von Lehre und Forschung erreicht werden. Der vorliegende Beitrag...

The most popular general univariate polarization indices for discrete (Esteban and Ray 1994), and continuous (Duclos, Esteban and Ray 2004) variables are combined and extended to describe the extent of polarization between agents in a distribution defined over a collection of many discrete and...

The most popular general univariate polarization indexes for discrete and continuous variables are extended and combined to describe the extent of polarization between agents in a distribution defined over a collection of many discrete and continuous agent characteristics. A formula for the...

This paper derives formulas for additive "chained volume measures" (CVMs) of GDP subaggregates depending on the underlying GDP quantity index. In turn, this paper explains why the formulas used in current practice yield nonadditive CVMs. This paper's additive formulas have significant practical...

This note identifies profit shifting in response to cross-countrydifferences in corporate tax rates as a source of productivitymismeasurement. To quantify the magnitude of mismeasurement, theprofit-shifting effect is isolated from other possible effects ofcorporatetax rates changes on real...

We ask individuals for their reservation price of a specified lotteryand deduce their Arrow-Pratt measure of risk aversion.This allows direct testing of common hypotheses on risk attitudes inthree datasets. We find that risk aversion indeed fallswith income and wealth. Entrepreneurs are less...

In this paper we derive a structural measure for labor market density based on the Ellison and Glasear (1997) Index for industry concentration. This labor market density measure serves as a proxy for the number of workers that can reach a certain work area within a reasonal amount of traveling...

Most measures of vulnerability are a-theoretic and essentially static. In this paper we use a stochastic Ramsey model to find a household's optimal welfare and we measure vulnerability as the shortfall from the welfare attained if the household consumed permanently at the poverty line. The...
